Since there is a report of "causes skin burns" (ICSC (2005)), the substance is highly acidic with a pH of approximately 1 (20 degC, 50 g/L) (GESTIS (access on Sep. 2009)) and the substance is classified into C; R34 in EU classification (EU-Annex I (access on Sep. 2009)), the substance was classified into Category 1.
3 Serious eye damage/eye irritation Category 1 Danger H318: Causes serious eye damage P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P310: Immediately call a POISON CENTER or doctor/physician.
There is a report of "causes severe deep burns to eyes" (ICSC (2005)). The substance is highly acidic with a pH of approximately 1 (20 degC, 50 g/L) (GESTIS (access on Sep. 2009)). The substance is corrosive to skin. The substance was classified into Category 1.
